Oil Immersed Distribution Transformer Inspection

In order to ensure the safe operation of oil immersed distribution transformer, oil-immersed transformers also need to be inspected. Oil-immersed transformers must be inspected every day to ensure the safe and efficient operation of oil-immersed transformers. How does the oil-immersed transformer do the relevant inspection work?

Inspection knowledge of oil immersed distribution transformer manufacturers

1. Whether the load current is within the rated value range, whether there is a strong change, and whether the operating voltage is normal.

2. Whether the oil level, oil color and temperature exceed the specified value, and whether there is oil leakage.

3. Whether the porcelain waterproof casing is cleaned, whether there are cracks, damage and dirt, charging and discharging, and whether there is discoloration or overtemperature when touching the terminals.

4. Whether the discoloration level of the silicone rubber in the damper is already saturated, and whether the sound of the transformer operation is normal.

5. Whether there is gas in the gas relay, whether it is full of oil, whether the laminated glass of the oil level gauge is cracked, and whether the diaphragm of the explosion-proof pipe is detailed.

6. Is the transformer casing, high-voltage arrester, and neutral grounding good? Is the transformer oil gate valve normal?

7. Whether the windows, doors, venetian blinds, iron mesh guardrails and fire-fighting equipment in the transformer room are intact, and whether the transformer is basically deformed.
